TRACTION-ENGINE.

SPECIFICATION forming part of Letters Patent No. 400,846, dated April 2,1889.

Application filed June 6, 1888. Serial No. 276,275. (No model.)

To all whom it may concern:

Be it known that 1, CHARLES O. HEGGEM, a citizen of the United States,and a resident of Massillon, county of Stark, State of Ohio,

have invented a new and useful Improvement in 'lraction-Engines, ofwhich the following is a full, clear, and exact description, referencebeing had to the accompanying drawings, making part of thisspecification.

My invention relates to improvements in traction-engines; and itconsists in providing means whereby the jar on the foot-board may bereduced; also, in providing means to rostore alignment of theaxle-spindles; also, in

providing means fol-arresting the momentum of the machine.

lVith these ends in view my invention relates to the detail andcombination of parts, as herein described, and set forth in the claims.

Figure l is a side elevation of a fragment of a portable engine,illustrating my invention. Fig. 2 is a vertical sectional view of thespindle-frame, spindle-supporting frame, and spindle. Fig. 3 is anisometrical view of spindle and frame.

Similar letters of reference indicate corresponding parts in all of thefigures of the accompanying drawings.

As my invention is applicable to many of the traction-engines now inuse, I will proceed to describe it, referring to the parts not thereininvolved only as conjnnctional thereto.

A represents a steam-boiler; B, the fire-box,

3 5 to the sides of which are secured spindlesupporting frames 0, havinga back portion, as D, adapted to conform to the side of the fire-box,and side plates, at, of such width as to secure the axle-frame fromrotation, and a bottom portion, 1), as a support for the spindleframeand a bearer for the spring F. The spindle G is formed of metal, towhich is welded a spur, as H, on the lower end of which there isprovided an annular screw-thread,

f. These parts, as shown in Fig. 2, are placed in a mold and moltenmetal poured in said mold and about said parts to form a frame, as E, tohold the spindle in its proper working relation. The spindle and frameare placed in the supporting-frame C, the spur H passed down into andthrough the perforation cl, the upper end of the frame resting betweenthe side plates, a, and against the bottom portion, I). In the upperportion of the frame E there is provided a recess, g, in which is placed5 5 a plate, h, of hard metal, that rests against the bottom Z), andset-screws 7e are turned into threaded perforations in the recess g. Theinner ends of said screws rest on the plate 71. A cross-bar, Z, securedto the sides a, spans the upper endof the boX port-ion of the frame C,

as shown in Fig. 1.

Below the bottom I), about the perforation (I, there is provided a shortsleeve, m, about which is placed a spiral spring, F, the spur H passingthrough said spring and a keeper, n, and nut O.

The weight of the machine is carried on the spindles G, resting on thehubs of carryingwheels K, one of which is removed to better expose theparts, and on the springs F. To provide for the vertical movement of theboiler caused by the vibrations of the spring, the frame E will movevertically in the frame C, the plate h sliding on the back and the spurin the perforation (Z in the bottom I), and to set the spindles indesired alignment the setscrews 7c may be turned in or out, as the casemay be, by which the top portion of the frame E may be moved out or into raise or lower the outer portion of the spindles G, and should thewheels K incline inwardly at the top, as is usual with such machines,the setscrews 7.: may be turned in and the outer portion of the spindlesthrown down, thereby placing the wheels in their properdesired position.

The wheels may be secured on the spindles with a nut in the usual way.

The foot-board L is supported on a U shaped 0 metal frame, M, the endsof which are passed through loops 1) and pivotallysecured to the frame0, as shown at J. The loop p is provided with a downwardly-projectedstem, 1', that is passed down through a spiral spring, 5 S, said springresting on a bracket, t, thus providing a yielding support for thefootboard, on which is carried a tank of water and a supply of fuel toprovide against breakage and for the comfort of the operator. I00

To arrest the momentum or movement of the machinc,a brake is provided,consisting, essentially, of a face-wheel, N, integral with or secured togear-wheel O, which is one of the train of gear-wheels connectingadrivingpinion on the engine-shaft Z with a wheel. similar to wheel Y onthe carrying-wheel K, re moved, as before stated, and a flexible shoe orband, N, placed about the face-wheel N and pivotally secured to alever-plate, 1-, loosely mounted on a stud-pin, n, said lever 1connected by an adjustable link, Q, to a foot-lever, R, which ispivotally secured to frame (1. Under said lever B is provided a spring,10, secured to the frame G, the free end of which rests under andagainst the lever. The energy of said spring is exerted upwardly toraise the lever, and thereby remove the shoe from the face of the wheelN, substantially as shown in Fig. 1. 'lobring the parts into action, thefoot of the operator is pressed on the free end of the lever B.

Having thus fully described the nature and object of my invention, whatI claim as new, and desire to secure by Letters Patent, is

1. 'lhe combination, in a portable engine, of a spindlc-supportin gframe, (I, having project ing side portions, a, a bottom portion, I),having a perforation, (Z, spindle G, a spindle-frame having adownwardly-projected portion, II, a spiral spring, F, secured aboutsaidportion, and an upwardly-projected portion adapted for lateral adj ustment, and means for securing said portion. in desired adjustment,substantially as described, and for the purpose set forth.

The combination, in a portable engine, of a spindle-sup lorting frame,(I, and a spindleframe, E, looselysecured to said frame U and adaptedfor vertical vibration and lateral adj ustmcnt, substantially asdescribed, and for the purpose set forth.

3. In a portable engine, the combination of the spindle G, and aspindle-supporting frame having an upwardly-projected portion, E, and a(.lownwardly-projecting portion, ll, substantially as described, and forthe purpose set forth.

l-. The combinal ion, in a portable engine, of

the U-shaped foot-board support, the ends thereof pivotally secured tothe sides of the fire-box, and su pporting-sprin gs, substantially asdescribed, and for the purpose set forth.

5. In a portable engine, in combination with a U-shaped foot-boardsupport pivotally se cured to the lire-box portion of the boiler, aspring supporting-l)racket, t, spring 3, andv loop 71., substantially asdeseribed,and for the purpose set forth.

(3. In a portable engine, a brake composed, essentially, of abrake-wheel, N secured to the gear'wheel (1), a flexible shoe, N,pivotally secured at both ends to a lever, 1, stud 7), adj ustable linkQ, foot-lever R, and a spring, w, fixed at one end to the engine andbearing with its free end against the under side of the lever R,substantially as set forth.

7. A steam-engine having an. axle and an adjusting device in connectiontherewith to regulate the inclination of the axle, substantially as setforth.

8. A steam-enginehaving a vertically-yieldingaxle and an adjustingdevice in connection with the axle to regulate the inclination of thesame, substantially as set forth.

E). In a portable steam-engine, the combination, with thespiudle-supportii1g frame 0, of a spindle-frame, E, vertically movablein said frame 0 and provided with a recess, g, a block, 71, fitting insaid recess, and a setscrew, 7t, for separating the upper ends of saidframes, substantially as set forth.

1(). In a portable engine, the combination of the pivoted foot-boardsupport, the fixed spring supporting-bracket, the loop embracingbranches of the said footrlmard support and provided with a stem workingin an aperture of the spring-sup mrt, and a spring oncircling the saidstem and engaging, respect ively, with its ends the loop and thespringsupport, substantially as set forth.

In testimony whereof I have hereunto set my hand this 23d day of May, A.I). 1888.
